Abstract: In an embodiment, a UE selects between RS collision protocols to selectively monitor, on downlink resource(s) scheduled with overlapping transmissions of first and second RS types, either the first RS type or neither RS type. In another embodiment, a base station determines that a downlink resource(s) are scheduled with overlapping transmissions of first and second RS types, punctures the second RS type, and selectively transmits the first RS type on the overlapped downlink resource(s). In another embodiment, a base station establishes non-overlapping NPRS and eNPRS transmission schedules.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a configuration for identifying narrowband reference signal (NRS) tones that are to be received in association with a scheduled paging occasion, wherein the NRS tones are configured to be received via a non-anchor carrier regardless of whether a page is to be received in connection with the scheduled paging occasion; and receive the NRS tones via the non-anchor carrier based at least in part on the configuration. Numerous other aspects are provided.

Abstract: Aspects directed towards sounding reference signal (SRS) antenna switching are disclosed. In one example, an SRS configuration is received from a network in which at least four antennas of a scheduled entity are configured based on the SRS configuration. Here, the SRS configuration configures at least one antenna to simultaneously support SRS antenna switching and an uplink (UL) multiple-input multiple-output (MIMO) communication. An SRS communication is then transmitted according to the SRS configuration. In another example, a transmission capability reporting is received from a scheduled entity comprising at least four antennas. A determination is then made of whether the scheduled entity may simultaneously support SRS antenna switching and an UL MIMO communication. An SRS configuration is then generated for the scheduled entity based on the determination in which a default SRS configuration configures at least one antenna to simultaneously support the SRS antenna switching and the UL MIMO communication.

Abstract: Disclosed are techniques for transmitting and receiving an extended narrowband positioning reference signal (NPRS) sequence. In an aspect, a base station generates the extended NPRS sequence and transmits, to at least one user equipment (UE) over a wireless narrowband channel, the extended NPRS sequence. In an aspect, a UE receives, over the wireless narrowband channel, an NPRS of a first subset of the extended NPRS sequence and measures the NPRS of the first subset of the extended PRS sequence. In an aspect, the extended NPRS sequence may be a function of a plurality of slot numbers of a plurality of slots of a plurality of sequential radio frames and a plurality of symbol indexes of a plurality of symbols of a single physical resource block.

Abstract: A method, an apparatus, a base station, a user equipment (UE), and a computer program product for wireless communication are provided. The base station may encode a wakeup signal so that a preamble of the wakeup signal indicates whether the wakeup signal is relevant to the UE. The UE may select a technique for detecting the wakeup signal based at least in part on a partial, full, or no synchronization. In some aspects, the wakeup signal may be encoded with a system frame number. In some aspects, wakeup signals for guardband/standalone UEs are provided. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications at a network entity. The network entity is configured to transmit a legacy paging message to a user equipment via a first set of resources, and a pre-paging message to a user equipment via a second set of resources. The second set of resources is used if one or more conditions are met. The network entity can also perform one or more actions after transmitting the pre-paging message.

Abstract: Methods, systems, and devices for wireless communication are described that provide for indicating device capabilities and/or device type or category, such as UE-to-UE direct communications via a PC5 interface, for aircraft-to-everything (A2X) communications. An A2X configuration may be provided that allows aerial UEs, such as unmanned aerial vehicles (UAVs) to indicate support for specific A2X functions. A2X functionalities may indicate support for transmit and receive communications, receive-only communications, or transmit-only communications. UE capability for A2X communications may be provided using one or more A2X-specific capability bits in a vehicle-to-everything (V2X) capability report or a sidelink capability report, that may individually or jointly indicate support for broadcast remote identification (BRID) transmissions, detect-and-avoid (DAA) transmissions, both, and/or other A2X communications. Further, a UAV may report one or more access link capabilities related to UAVs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may apply a discrete Fourier transform (DFT) orthogonal cover code (OCC) to a first virtual hop that is associated with a physical uplink control channel (PUCCH) transmission. The UE may apply the DFT OCC to a second virtual hop that is associated with the PUCCH transmission, wherein the first virtual hop and the second virtual hop are associated with equal quantities of orthogonal frequency-division multiplexing (OFDM) symbols, wherein a size of the DFT OCC is based at least in part on the quantities of OFDM symbols, and wherein the first virtual hop and the second virtual hop are not associated with physical frequency hopping. Numerous other aspects are described.
